The global market for personal and entry level storage (PELS) is driven
by an increase in the amount of data generated and the need to manage
this data. Growing concerns surrounding data storage and data backup is
also contributing to the increasing global demand for PELS devices.

Driven by a continuous rise in the volume of data generated and growing
concerns towards data backup and security, the global market for
personal and entry level storage (PELS) systems was valued at USD 5.0
billion in 2012 and is expected to reach USD 39.49 billion by 2019,
growing at a CAGR of 35.1% during the forecast period from 2013 to 2019.
Individuals and entry level business organizations have started
recognizing the need and importance of data storage and data backup,
which is in turn, contributing to the demand for PELS devices.

In today's knowledge driven era, it is extremely important to store and
manage information. Growing use of internet media, online gaming, and
others have created unprecedented demand for storage architectures
worldwide. The information generated globally is expected to double
every two years. In 2011, world created around 1.8 ettabytes of data
and by 2020, this number is expected to be around 50 times the amount of
information in 2011. To meet the data storage demands, small and
mid-sized organizations are adopting different kinds of data storage
architectures such as network attached storage (NAS), direct attached
storage (DAS), cloud based storage and others. NAS is the most widely
used data storage technology in entry level business organizations as a
single storage device is shared along the network for all the users.

This type of architecture reduces the overall equipment cost and is a
cost effective method of storing data in business networks. Cloud
storage is rapidly evolving data storage service which is expected to
grow at a CAGR of 48.5% during the forecast period from 2013 to 2019. In
this type of data storage, data is stored on the virtual servers located
across the world that are generally hosted by third parties. As data is
stored online, it can be accessed from anywhere in the world without the
need for a storage device for the user; however, data security is a
major concern associated with cloud storage as multiple copies of data
are generated and stored on distinct servers located across the world.
